Before she was a superstar, Fergie was a meth addict. The singer grew increasingly gaunt and paranoid and left the girl group she was part of at the time, Wild Orchid. One day, while high, she wandered into a church and then became convinced that the FBI was outside waiting to arrest her.

So I had a conversation with God… and I said, ‘Alright, if I go out there and the FBI and the SWAT team’s not out there, then it’s the drugs and I’m stopping.’ I went outside of the church… and there was no SWAT team, there was no FBI, just me and God. And I kept my promise. That day. That was it.

So if she had walked outside and there had been a swat team and several FBI agents, would she still be doing meth? It sounds to me like she was ready to quit and it happened. Good for her on this point. To bad for her that she thinks she needed a sign from an imaginary “Magic Sky Daddy” to do something that she obviously knew was a good idea on her own.
